I think maybe the strikes with the airlines had something to do with it the past few weeks. I had some friends that didn't want to commit to trips here because they read about airline strikes and potential to get stuck here Maybe people were in the same boat.
I have noticed this trend too. I have also seen some official statistics that say tourism has slowed down. Argentina is expensive now. Crazy how much prices have jumped up. 70,000 pesos for a Milenesa at El Preferido de Palermo. Crazy. 35,000 pesos for a steak sandwich in Recoleta.
At some point I would think tourists will just go to Europe. They have cheaper flights and besides hotels, I think food is probably cheaper there.
